Running can be painful

Well, truth time, running hasn't been going so well.  I have some issues with pain in my left leg.  It has been getting progressively worse.  My last long run (21 miles) was 3 weeks ago.  This morning I ran 1 mile before pain made me walk.

The marathon is 7 days away.  I have PT scheduled for this week, which might help. But the prognosis is not good.  I made a decision while walking home-

This will not be my best marathon, but it will be my first.
